Note that the export has the same info that Stock Central. Of all the fields that you have in the image, the only one that has totals is the Current Stock.
Regarding your question about the possibility to export a CSV, I recommend you to use our premium add-on ATUM Export Pro. With this add-on you will be able to export almost any kind of data in your site in CSV format.
I recommend you to take a look at the documentation, where you will find useful info about how it works: https://forum.stockmanagementlabs.com/t/atum-export-pro-documentation
